Answer:
m = 4
Step-by-step explanation:
The complete question is:
Given:
6.33 x 10
⁹ / 1.79 x 10⁵ ≈ 3 x
To find:
To best estimate the quotient in scientific notation. what number should replace m?
Solution:
The equation is:
6.33 x 10
⁹ / 1.79 x 10⁵ = 3 x
Let x = 9 and y = 5 then the above equation becomes:
6.33 x / 1.79 x
= 3 x
Since we know that the exponent property is:
quotient
Now converting the given equation in the form above we get:
6.33 / 1.79 x
6.33 / 1.79 x
Now the quotient is 6.33/1.79 ≈ 3.536313
quotient x
3.536313 x
Since 9-5 = 4 So
3.536313 x
3.536 x
Hence
6.33 x 10
⁹ / 1.79 x 10⁵ ≈ 3.5 x
Hence m = 4
Answer:
Step-by-step explanation:
We have been given a graph of a rectangle. The area of the shaded section is 63 square units. We are asked to find the value of x.
We can see from our given graph that shaded section forms a trapezoid, so we will use area of trapezoid formula to find the value of x.
, where, a and b represents the parallel sides of trapezoid and h represents height of trapezoid.
Upon substituting our given values in above formula we will get,
Upon dividing both sides of our equation by 3.5 we will get,
Let us subtract 7 from both sides of our equation.
Therefore, the value of x is 11 units.
Answer:
x =
Step-by-step explanation:
given
=
( cross- multiply )
5(x + 1) = 33
5x + 5 = 33 ( subtract 5 from both sides )
5x = 28 ( divide both sides by 5 )
x =
